Network X (4.8.2)
When I tried, http://networkx.lanl.gov/ was not available. I used http://networkx.github.io to read documents instead.
For installation, I dis as follows. sudo was required because of authorization problem.

Write following code and saved as name 'exnetworkx.py'.
import networkx as nx import matplotlib from nltk.corpus import wordnet as wn def traverse(graph, start, node): graph.depth[node.name] = node.shortest_path_distance(start) for child in node.hyponyms(): graph.add_edge(node.name, child.name) traverse(graph, start, child) def hyponym_graph(start): G = nx.Graph() G.depth = {} traverse(G, start, start) return G def graph_draw(graph): nx.draw_graphviz(graph, node_size = [16 * graph.degree(n) for n in graph], node_color = [graph.depth[n] for n in graph], with_labels = False) matplotlib.pyplot.show()
Then try to draw a graph.

It seems 'pygraphviz" is required. Let's install via pip.
